Abstract
In a method of manufacturing an image display apparatus, a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light are seal-bonded in a seal bonding chamber in which a vacuum atmosphere is realized. An aging step for the electron-emitting device is performed before the step of seal-bonding.
